For example, if the input is 1 and the **input's weight is 0.2** the input will be decreased to 0.2. These weighted signals are then added together and passed into the activation function.

1. what is input weight? 2. how to calculate that weight?3. Threshold value will be always fix in ANN (using activation function of threshold).4. if value is fixed that what will be the that range.?5. what is hidden layer?does it means combination of sum + activation function is called hidden layer?
